Ch.10 Flashcards
The direction to which a body is projected with respect to the horizontal
Angle of projection
The highest point in the trajectory of a projectile
Apex
Occurring over a designated time interval
Average
Vector quantity incorporating both angle and speed of projection
Initial velocity
Occurring during a small interval of time
Instantaneous
The form, pattern, or sequencing of movement with respect to time
Kinematics
Formulas relating displacement, velocity, acceleration, and time when acceleration is unchanging
Laws of constant acceleration
The rate of change in linear velocity
Linear acceleration
Change in location/position, or the directed distance from initial to final location
Linear displacement
The rate of change in location/position
Linear velocity
The most common international unit of length, on which the metric system is based
Meter
Body in free fall that is subject only to the forces of gravity and air resistance
Projectile
The magnitude of projection velocity
Projection speed
The horizontal displacement of a projectile at landing
Range
The difference between projection height and landing height
Relative projection height
The flight path of a projectile
Trajectory
Movement Kinematics is also referred to as
Technique
All objects will follow a known path
Parabola
Sum of distance traveled (Length)
Linear distance
TF: When a runner completes a lap around a 400 m track, their distance traveled and their displacement are the same
False, bc initial and final are the same, displacement=0
What is an example of the distance covered by a moving body the same as its magnitude of displacement?
When a skier traces a RECTILINEAR path when traveling down a slope
Distance covered / time taken to cover it
Linear speed l/t
The change in position or displacement that occurs during a period of time
Linear velocity
The value of a quantity at a
particular moment in time
Instantaneous velocity
Occurs over a designated time interval
Average velocity
TF: Acceleration is only equal to zero if there is no movement
False,
Velocity can be constant to have 0 acceleration
The Vertical component is influenced by __ and the horizontal component is not
Gravity
The vertical component relates to the __ achieved by the projectile
The Horizontal component of motion relates to the __
Range
What factors influence the trajectory of flight path of a projectile
Projection angle
Projection speed
Relative height of projection
If projection angle is perfectly
